 Subject: Overheating '93 5.2L
IP: Logged
Message:
I am looking for a few ideas on why my Dakota is still overheating when I run the AC. It only overheats when I am sitting still with the AC running (like at a stoplight). I do live in a high heat/humidity area, but I would think it wouldn't overheat. I have flushed the cooling system, installed a 180° thermostat, removed and cleaned the fins on the radiator as well as installing a new fan clutch. The truck has 150k miles on it and runs good other than the temp. Any help or ideas would be greatly appreciated
Thanks
Charles

Try installing a pusher fan between the radiator and the airconditioner radiator looking thing, not sure what its called. That will push air as the fan with the clutch is pulling air. Did you do a complete cooling system flush? what condition is your radiator in, i just replaced mine that had 141,000 miles on it. My truck is a 92 LE with the 5.2 motor.

I did the best flush that I am able to do. First, I ran the truck with one of the "radiator flush" chemicals in it following the directions. I then reverse flushed the system with a Prestone flush kit.
The radiator seems to be in good shape, but I can't really tell if some of the tubes are plugged inside.
I was trying to avoid installing an electric fan at this time because I beleive that the truck should be designed to stay cool without it. It looks like a radiator swap might be the best thing to do at this point. I would then follow that up with a LARGE electric fan to replace the clutch fan so pick up some HP.
Thanks

Radiator would be the best idea, run a good brand of antifreeze! Make sure your mixture is right on 50 /50 50% water 50% antifreeze

Charles,
Your right, you should not overheat w/the stock setup and need an electric fan.
The radiator may still be blocked. You have allot of miles. I think you may need to take it to the shop b/c you have done everything you can do except rodding the radiator or getting a new one.

you stated that the truck has high miles and it only over heats when at idle and air on,have you checked out the clutch fan? when they start to go
they will free spin easily and not pull as much air over the radiator at idle speed ,not much of a problem when up to speed and air pushed through the radiator,it sound like you checked the other areas?FYI hope it works.
